Heroes of Might and Magic V [Game Discussion]

Perhaps the map was intentionally made small so that the player couldn't spend too long pressing the defense button and accumulating ATB (suggestion by Katrin). Honestly, how can one thoroughly criticize and dismiss a small map if most people haven't even tried it themselves and are only relying on other people's opinions...?
And as for the "Rules of Mines" and "Fire Wall" spells... even in part 3, they were not very popular spells... and I also didn't see "Fire Wall" in part 5.
